I was just wading through Amazon looking at my recommendations and a few of the other blood type books came up. I didn't realize that the Ounce of Prevention book was by James D'adamo instead of Peter. Took a look at the contents and noticed sub-blood types. (Oa, Ob, Ao, Ab, Bo, etc.) While trying to figure out my blood type I actually wondered if something like this was possible since I demonstrate traits from both of my parents. I may have to buy this book. This subject is absolutely fascinating to me. I haven't seen Dr D talk about sub-blood types. (Unless I missed something which is definitely possible). Are these sub types still taken into account?

swami interphase has all this and more computed into the system, the complexity is mind blogging!

have you already thought of running yours?

I have ran my swami many times and I did see a place for sub typing but I thought it was for A's A1 and A2? I need to go investigate! :D

James D'Adamo has a different take on blood types than his son. I haven't read his latest book (as my library didn't own a copy the last time I checked.) I still want to read it, just to get an idea about what other blood type diet theories are out there, but I'm following Dr Peter's SWAMI and I'm happy with it.

If I was going with one of the "book diets" then I'd take a much closer look at Ounce of Prevention; and pick and choose the portions of each book (Dr Peter's blood type diet, Dr Peter's genotype diet, and Dr James' blood type) that best suited me and I'd try to put together something individualized based on which foods from each list worked the best for me. But since I have SWAMI I feel no need to use any of the "book diets" at all.

I have to give Dr James D'Adamo incredible credit for coming up with the blood type diet theory in the first place- Peter could never have accomplished all that he has without the foundation his father developed years ago. But I can't comment on his newer work because I haven't yet read it.

Well said Ruth. Lola, is this already integrated into the system or is it something I can enter in? I see A1 A2 subtype, lewis, MN, and hapologroup. I don't really understand these nor did I get anything other the blood type and Rh factor from the Dr so I'm really curious

I have read the book. It is from 2010. If you search there were several threads soon after it was released.

Ounce of Prevention is a different approach than what Peter D'Adamo uses. Jame's approach to blood sub-groups is different than any treatment of blood sub-groups than I have read any place else.

The results from following the methods in the book yields a diet for me that is very similar to my SWAMI diet.

I think the Ounce of Prevention diet would work quite well for me, but I did not test it.

I choose to follow SWAMI diet since I am comfortable with its scientific foundation. I am uncomfortable with the science James used to arrive at the diet plans in his book.

In his book he used both sub-blood type and sub-blood group. I would be more comfortable with his work if he had just used terms that did not already have a different meaning than he intends.

The blood sub-group system of James' Ounce of Prevention book is not used in any of the D'Adamo systems.

I don't mean to be argumentative but if he is the one to discover all of this information in the first place and has studied it the longest why is this dismissed? What is wrong with his science? Have the other serotyping factors proved more effective? Again, I'm sorry if I sound harsh but I want to learn.

to each their own......it is all good.....

Quoted Text

Dr D: We might say that the differences between my books and those of my father mirror the differences between the two currently co-existing generations of naturopathic physicians.

It should be obvious that I did not have anything to do with this book. We all know people who just have to do things their own way. But I happen to love my dad, so whatever it is, it is. I'm just happy for him.

I think that is what actually became his last book.

Have the other serotyping factors proved more effective?

Serotyping is not used to determine blood subtypes in Jame's system.

Instead you answer a series of questions like "Do you prefer subdued colors around you such as blue or greens?" or "Do you prefer running to yoga?" to determine what you blood subtype is.

why is this dismissed?

If you want to know about the system in Ounce of Prevention, I encourage you to read the book.

The system described in Ounce of Prevention is different from James' earlier books and any of Peter's published work.

Because the system is different from Peter's systems, I try to avoid discussing it here since it generally just confuses people.

There is a website dedicated to James' work and it discusses the concepts in Ounce of Prevention.

The systems are not compatible. So one needs to decide which they follow. Both work much better than the standard American diet.

I have chosen SWAMI, that works for me.

Other may find that Ounce of Prevention is better for them.

I have the book and I think it is very good. My sense is that James' work is the base and it is an interesting book and worth a read. Different thinking in the sub types, and food felt more limited.Clearly Peter has taken that further or in a different direction, or both.I like using the Swami and Blood Type Books by Peter, but I do think James work is very good and people using either one would obviously improve their health.Lin

I have Dr. James D'Adamo's Just an Ounce of Prevention book and found it very informative. I have always wondered about the connection to the parent from whom we did not inherit bloodtype. Dr. James does address this. I am an A+ as is my mother. My father is an O-. It is interesting that I identify with him in so many more ways (allergies, diet, body type, way we think) than my mom.Personally, I find Dr. James diet (for me an "Ao") quite restrictive as compared to Dr. Peter's swami. I like that Dr. James would allow me to have sweet potatoes, pears, peaches, and apricots :D but don't like that he would not allow anydairy of any kind...none! :o He makes a good point about Ao's needing the little extra animal protein. I know for certain that if I couldn't have turkey when I felt like my body needed it, I would be weak/sick. I agree that whether one follows the father's diet or the son's, they are the healthiest. ;)I am satisfied with my swami and as was previously mentioned, admire the intricate and abundant science it entails. :)

Cajun,I also found the parental blood type input interesting. My mother being A/B and believe my father an A, it makes me Ab in James book and I could relate to some of the things mentioned there.I wonder if that is captured a different way in Swami/Genotype for example being a blend of Teacher/Explorer vs Teacher/Warrior for an A?Lin

I read Dr James D'Adamo's 1980 book. That is the general foundation of the blood type diet. In a nutshell, that book focused on macronutrient ratios- type O's need more meat and less vegetable protein, type A's need more vegetable protein and less/no meat, Bs and ABs are somewhere in the middle. He didn't, at that time. delve into further individuality or figure out which specific foods are good or bad for which individual. In 1980, nobody had published anything saying "type O individuals should not eat wheat or milk." I now know that many of my health issues growing up would have been prevented if anybody had known not to feed me those two foods.

Dr James' most recent book was researched and published after Dr Peter was already an adult doing his own research. At that point, their approaches diverged. But without the basic foundation Dr James came up with several decades ago, none of the modern BTD information would be available now. So I'm giving Dr James credit for getting the whole thing started. But I'm unfamiliar with his more recent research or the direction he's gone since Dr Peter entered the scene.

Did anyone try the subtype diet and would like to share their experience? I would be interested to hear your input.

I will tell you that I follow my swami nearly 90%. Dr.James Ao diet for me is very much like my swami ..other than it restricts the variety of food in each group and gives me no dairy.....I could try to go without cheese but... ??)Dr. James says its good for Ao to eat sweet potatoes, peaches, pears and apricots.Well, I never actually gave those up...those have been among my 10% "cheats" on my swami.( along with peppers, black tea, and sometimes tomato sauce)Honestly, I might be better off avoiding all dairy, but I know I tolerate/enjoy eating sweet potatoes and those fruits! No problem! ;)I am not advocating that anyone ignore some of their swami...I am human with faults and do try to be totally compliant , but when I am not, oh well, I know what really affects me and what doesn't. ;)( wheat and non-compliant cheese :o :P)
